Package
General Descriptions The MPM series is a full molded hybrid IC which contains a non-insulated buck type DC/DC converter in one package. A power supply circuit can be composed in a simple way by using this hybrid IC which requires a small part count. By connecting only an input smoothing electrolytic capacitor, an output smoothing electrolytic capacitor and an output voltage setting resistor, the hybrid IC can be operated. Because of this simple composition, time required for design evaluation is significantly reduced. Since a power inductor is built in, it is not required to select and evaluate the inductor separately. By adopting a full molding package which can be fitted to the heat sink by screwing, board mounting can be made in self-supporting state without the heat sink subject to the output voltage setting and load conditions.
